Patent CA-2343301-A1 (CA)
Inventor: NASS PETER
IPC: C03C3/097
Filed: 2001-04-05
Abstract: A cooking surface for a cooktop. Encrusted, spilled, or overflowing food is deposited on the cooking surfaces of cooktops during cooking and the removal of such residue is difficult because the surface of a cooktop is typically rough and uneven. The invention teaches the manufacture of an easy-to-clean glass ceramic cooktop from a floated glass ceramic. As a result of the increased use of controls in cooking devices, an increased number of displays are also being used under the surface of the cooktops. The invention provides a cooktop with a smooth, distortion-free surface that is easy to clean. The invention also relates to window panes for enclosed hot areas with high temperatures, which are typically made of transparent glass ceramic. When used as windows in warming stoves or in self-cleaning ovens, combustion residues are thereby deposited on the windows, which residues must then be removed. It is difficult to clean a window of this type, because the surface of the transparent glass ceramic that is manufactured using conventional methods is typically structured and uneven.      The invention teaches the manufacture of an easy-to-clean class ceramic window body from a floated glass ceramic that has a specified surface quality that is comparable to that of a floated soda lime glass pane. The invention also relates to a stove for cooking food with an easy-to-clean oven window and an easy-to-clean cooktop.

Inventor: RICHARDSON ROBERT F
IPC: G06F17/30
Filed: 1999-09-28
Abstract: A method of extracting significant phrases from one or more documents stored in a computer-readable medium. A sequence of words is read from the one or more documents (110) and a score is determined for each word in the sequence based on the length of the word (120). The score for each word in the sequence is compared against a threshold score (130). The sequence of words is indicated to be significant phrase if the number of words in the sequences that have a score greater than the threshold score equals or exceeds a predetermined number (140).

Title: Poursuite adaptative de voies a l'aide de sequences pilotes
Inventor: ARSLAN HUSEYIN
IPC: H04L7/04
Filed: 1999-10-12
Abstract: Procédés et systèmes qui utilisent des pilotes dans une séquence d'information pour reconditionner périodiquement un estimateur de voie. Par conséquent, un dispositif de poursuite de voie peut être synchronisé à l'aide d'une séquence de synchronisation et ensuite périodiquement reconditionné à l'aide de symboles pilotes connus. En outre, l'utilisation de pilotes peut permettre la détection d'erreurs dans des estimations précédentes de voie. Lorsque des erreurs sont détectées, une nouvelle estimation de voie peut être utilisée sur la base du reconditionnement à l'aide de symboles pilotes et, éventuellement, des erreurs précédentes dans l'estimation de symboles peuvent être corrigées. Par conséquent, il est possible de réduire la propagation des erreurs grâce à un reconditionnement basé sur des symboles pilotes.

Patent CA-2348496-A1 (CA)
Inventor: BARONE STEPHEN
IPC: G08B13/193
Filed: 1999-10-27
Abstract: Methods and apparatus are disclosed for improving the sensitivity, angular resolution and range of motion detectors, occupancy sensors and similar systems. Specifically, an improved infrared input section is described which employs at least one additional lens, possibly segmented, before a lens array.  This pre-focusing lens collects incident infrared radiation over the entire entrance aperture and partially focuses it onto one element of the lens array.  The final lens array which focuses the radiation onto a detector may be an array of Fresnel lenses as in the prior art, an array of microlenses or a diffractive optics array. It is also possible to implement this system in such a way that moving infrared sources at any angular orientation will be detected as opposed to prior art systems in which only sources which cross the planes separating an array of angular sectors are detected.

Abstract: What is proposed is a mixer for mixing at least two flows of gas or other Newtonian liquids. What is provided is a main flow channel (1) through which a first flow of gas passes, with an incorporated surface (7) that is arranged therein and which affects the flow. This incorporated surface (7) is a vortex-generating disc with leading edges (8) that a oriented against the flow and about which the flow can move freely; its shape generates a component that acts in the direction of the main flow (9) of the gas flow as well as a component that acts transversely thereto. In order to ensure that an additional gas or liquid component is mixed in rapidly, provision is made such that the incorporated structure surface (7) has a chamber (13, 13a, 13b) into which a separate flow channel (5) for a second gas flow leads; and in that the chamber (13, 13a, 13b) has outlet openings (12) into the first gas flow on the rear side (10) of the incorporated surface (7) that faces away from the first gas flow.

Abstract: The aim of the invention is to provide a method for electrically contacting metal reinforcements in concrete which can be carried out at low costs and which also provides a means for preventing the concrete surface from having to be partially chiseled open and then filled in again. To this end, the invention proposes a method for electrically contacting metal reinforcements in concrete. According to the invention, the position of the metal reinforcement in the concrete is detected, a bore hole (4) extending right up to the metal reinforcement is produced in the concrete and a threaded rod (7) is anchored in the bore hole by way of an expansion anchor (6). Said threaded rod is screwed into the bore hole until it contacts the metal reinforcement in an electrically conductive manner.

Title: Reed switch
Inventor: SHIMOYAMA KEIJI
IPC: H01H36/00
Filed: 2001-12-11
Abstract: In the conventional fluid level detector, the reed switch is accommodated in the housing formed of an insulating material such as a resin or the like to prevent the reed switch from coming into direct contact with fluid and being electrically shorted. However, since such a construction requires the steps of storing and fixing the reed switch in the housing and leading out the lead therefrom, workability is low, the housing must be manufactured separately, and thus the cost increases.      Accordingly, a reed switch wherein at least the tubular bulb portion is molded with a hot-melt resin is provided.

Abstract: A dating related web site incorporates a number of services of interest to subscribers seeking a compatible mate or friend. A would-be subscriber first specifies profile information including authentication information, information relating to qualities desired in a friend and mate, and a screen image icon. The profile information is stored in a database associate with a web server hosting the dating site. The subscriber can then log onto the site and advantage the of chat room environments featured at the site. Rooms are hierarchically organized into lobbies and sub-lobbies corresponding to topics and sub-topics of discussion. In addition, the lobby and sub-lobby screens indicate the concentration of compatible participants in the rooms of corresponding lobbies and sub-lobbies, thus allowing easy navigation to a desirable room. In addition to manual navigation, the site features automatic navigation allowing the user to find a chat room with compatible participants automatically once a sub-lobby is selected. Upon participating in a chat session, the user and a participant may choose a "virtual date" option featured at the site to take advantage of a private chat environment and to view a private, date-related video clip
